WEATHER RESISTANT STEELS
Steel with superior resistance to atmospheric corrosion, commercially known as Corten, is a type of steel to which small amounts of phosphorus, copper, chromium and nickel, among others, have been added to make it more resistant to atmospheric corrosion.
Atmospheric exposure tends to form an oxidation patina on the surface of metallic materials, but in this case, due to the presence of phosphorus, the protective layer of the material continuously regenerates, forming a barrier against moisture, oxygen, and pollution and giving it a unique and uniform appearance.
This product stands out for its versatility and multiplicity of applications, namely of an aesthetic nature, with emphasis on the restoration of old buildings and structural parts/construction.
The material is available in geometric ties, strapped with steel bands, in hexagonal, square, and/or rectangular shapes. To facilitate handling (loading/unloading), all the ties are supplied with polyester straps suitable for the weight of the tie.
Each tie is supplied with a label attached by a metal clip, ensuring the identification of the product and consequently its traceability.
During manufacture, all tubes are coated with a protective oil, which has a high hydrophobing power, to protect the surface against corrosion. Unless otherwise stated by the customer at the time of the order/inquiry.
On shipment, all orders are accompanied by the respective inspection certificate according to EN 10204, in accordance with the product’s applicable standard.
Hot-dip galvanized tubes can be supplied, according to EN 10240 A.1/A.2 or ISO 1461, providing greater protection against corrosion.
Special tolerances must be requested when inquiring/ordering.
Possibility of removing the internal welding bead. Possibility of defining the position of the weld bead, according to target value and/or face of the tube.
Possibility of supplying tubes with chemical properties that guarantee their suitability for hot-dip galvanization.
Possibility to specify the CEV value at the time of inquiry/order.
It is possible to supply tubes that meet the requirements compatible with weldability at the corners according to EC3.
Capacity to supply tubes with specific lengths, requested at the time of inquiry/order.
Tubes can be supplied, according to the most demanding deformation capabilities.
The ties can be configured, according to the client's indications, at the time of the inquiry/order. Possibility of using packaging with anticorrosion protection (VCI).
Possibility of requesting specific laboratory tests, not foreseen in the applicable standard (anisotropy, salt fog, metallography, thickness elongation, among others)
